An in Vivo CT Imaging Study of GMA-Tulip, I-gel, and LMA Supreme (GLAM-II)
Recruiting now · Not applicable
Conditions studied: Supraglottic Airway Device
In brief
Laryngeal masks are core devices for supraglottic airway management, and the accuracy of their anatomical position directly impacts ventilation safety and the incidence of complications. Despite their wide clinical application, gaps remain in understanding their in vivo anatomical characteristics. This study aims to evaluate the in vivo anatomical features (e.g., insertion depth, anatomical alignment, tissue compression) of three laryngeal masks (LMA Supreme, I-gel, GMA-Tulip) using CT scanning in anesthetized patients undergoing CT interventional therapy, providing anatomical evidence for optimized laryngeal mask selection and complication prevention.
